JOHN M. COOMBS, OF HICKSVILLE, OHIO.

SYRINGE.

SPECIFICATION forming part of Letters Patent No. 394,250, dated December 11, 1888.

Application filed May 31, 1888. Serial No. 275,668. (No model.)

To all whom it may concern:

Be it known that 1, JOHN H. COOMBS, a citizen of the United States, residing at Hicks ville, in the county of Defiance and State of Ohio, have invented a new and useful Improvement in Injection-Syringes, of which the following is a specification.

My invention relates to an injection-syringe for the treatment of rectal diseases; and it has for its object to simplify and improve the construction of instruments of this character, to adapt them to be used by the patient or other inexperienced person without the assistance of a physician or a skilled attendant.

The invention consists in a certain novel construction and arrangement of devices, fully set forth hereinafter in connection with the accompanying drawings, wherein- Figure 1 is a side view of the syringe with the parts arranged for use. Fig. 2 is a front view of the same. Fig. 3 is a central vertical sectional view on the line 11' a; of 2. Fig. 4 is a similar view on the line a: of Fig. Fig. 5 is a transverse horizontal section on the line y 7 of Fig. 3. Fig. 6 is a detail perspective view of the sliding gage.

Referring by letter to the drawings, A designates the tapered nozzle of the syringe reduced to a point at its upper end and having a threaded opening, B, at its lower end 3 and O represents the funnel-sha1')ed discharge-tube, which is screwed in the said opening B, and is provided with the flexible conducting-pipe D. A stem, E, is attached to the rear side of the nozzle and extends up to form the tubular passage F, which is separated from the cavity G of the nozzle by the perforated or spray plate H, the perforations in which are inclined upward at an angle of about forty-five degrees. The upper side of the cavity G is also inclined upward toward the front side, and in the front side is a vertical slot, 1, opposite the perforated or spray plate and covered by the slide K, having dovetailed edges to engage dovetailed grooves in the edges of the slots. The lower end of the slide is provided with the thumbhold 76, to enable it to be operated to open or close the slot in the front side of the nozzle.

A depending arm, L, extends downward from the lower end of the nozzle on the front side, and the adjustable stop )1 is mounted thereon in the path of the lower end of the slide K, whereby the length of the .slot ex posed by the slide may be regulated by the position of the stop, for a purpose to be hereinafter described.

The sliding N is provided at its upper end with a horizontal plate, n, and the vertical slot 0 in the gage is mounted on the setscrew P, whereby it may be clamped at any desired point. The supply pipe or tube R is attached to the lower end of the stem E, and is provided with the pump-bulb S, to enable the water, cleansing solution, or medicament to be forced into the nozzle.

The operation of the syringe as follows: To discover the existence and location of ulceration in the rectum, the discharge-tube (J is removed from the lower end of the nozzle, and the latter is introduced into the rectum with its front side (for example) toward the rear of the patent, The slide is now slowly withdrawn, thereby allowing the mucus folds of the rectum to prolapse into the interior cavity through the slot, and by deflecting the light up through the nozzle the appearance of the tissue may be noted. \Yhen an ulcer is exposed, the nozzle is drawn down until the upper end of the slot is just above the ulcer, and the gage is then adjusted so as to bear against the body of the patient and prevent the nozzle from being further inserted. The slide is now withdrawn far enough to expose the entire length of the ulcer, and then the adjust-able stop is clamped at the lower end of the slide to prevent the further withdranal of the latter. The ulcer being now exposed, while the surrounding healthy tissue is protected, the discharge-tube is replaced and the pump is operated, thereby projecting the cleansingsolution directly upon the diseased tissue. The ulcerated mucus being prolapsed into the cavity of the nozzle, the spray which is thrown through the perforated plate completely envelopes and washes it, and the waste water flows down and escapes through the dischargetube. The cleansing operation having been satisfactorily completed, a medicament may be applied in the same manner. The upper end of the nozzle is solid, and as the slide'is removed the sides of the rectum prolapse into the slot and entirely fill the same, and therefore the escape through the slot of the cleansing-solution or the medicament is prevented, and the entrance into the nozzle of the fecal matter is also prevented. \Vhen the nozzle is to be Withdrawn, the slide is slowly pushed up and the nozzle is slightly drawn down to expel the prolapsed tissue from the cavity, (the upper inclined end of the cavity enabling the said tissue to slide out Without injury.) The upper end of the slide is rounded to enable it to be forced tightly against the upper end of the slot Without pinching the flesh.

Having discovered and located the ulcer and indicated by the gage and the adjustable stop the distance to insert the nozzle and the distance to Withdraw the slide, it will be obvious that any one may now introduce the nozzle and expose the ulcer to the action of the cleansing solution or medicament Without the assistance of a physician or other skilled person.

An ulcer of any ordinary length may be indicated on the depending arm by the position of the adjustable stop, and if the ulcer is too broad to be received between the sides of the slot one side thereof may be cleansed, and then the nozzle may be turned slightly to bring the other side into the slot. The location, however, of the ulcer is so indicated 011 the nozzle as to enable any inexperienced person to expose it.

Having thus described the invention, I claim- 1. In a syringe, the nozzle having a closed inner end and provided in one side with a slot covered by a suitable slide, the passage at the other side separated from the cavity of the nozzle by a perforated or spray plate arranged opposite the said slot, and the supply-tube connected to the said passage, substantially as specified.

' 2. In a syringe, the nozzle having a supplytube and provided with a closed inner end and a slot in its side fitted with a suitable slide, in combination with an adj ustable stop mounted on the nozzle in the path of the said slide, substantially as specified.

3. In a syringe, the combination, with a nozzle provided with a closed inner end and having a slot in its side, and thesupply-pipe connected to the cavity of the nozzle, of the adjustable slide K, mounted in the said slot, and the adjustable gage N, having a longitudinal slot mounted on a suitable clampingscrew on the nozzle and adapted to bear against the body of the patient to limit the insertion of the nozzle, substantially as speci- 4. In a syringe, the nozzle having a closed inner end, and provided with a cavity and a passage, F, separated from the cavity by a perforated spray-plate, in combination with a tube connected to the cavity, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in presence of two witnesses.

JOHN M. COOMBS.
